Embodiments of the present disclosure describe signaling of positioning measurement indications or measurement gap requests. Other embodiments may be described and claimed.

CROSS REFERENCE TO RELATED APPLICATION

The present application is a continuation of U.S. patent application Ser. No. 16/372,139, filed Apr. 1, 2019, and entitled “Inter-Radio Access Technology Positioning Measurements in New Radio Systems,” which claims priority to U.S. Provisional Patent Application No. 62/651,500, filed Apr. 2, 2018, and entitled “Inter-Radio Access Technology (RAT) Observed Time Difference of Arrival (OTDOA) Measurement in New Radio (NR) Systems,” which are hereby incorporated by reference in their entireties.

FIELD

Embodiments of the present invention relate generally to the technical field of wireless communications.

BACKGROUND

Observed Time Difference of Arrival (OTDOA) is a positioning method that makes use of measured timing of downlink signals received from multiple transmission points (TPs), comprising evolved NodeBs (eNBs), next generation eNBs (ng-eNBs) and Positioning Reference Signal (PRS)-only TPs, at the UE. A user equipment (UE) may measure the timing of the received signals using assistance data received from a positioning server, and resulting measurements may be used to locate the UE in relation to one or more neighboring TPs. A TP may be a set of geographically co-located transmit antennas for a cell, part of a cell or a PRS-only TP. TPs may include a base station (for example, an ng-eNB or gNB) antennas, remote radio heads, a remote antenna of a base station, an antenna of a PRS-only TP, and/or the like. Additionally, in some implementations a single TP may correspond with one cell, while in other implementations, one or more TPs may form one cell. A PRS-only TP may be a TP that only transmits PRS signals for PRS-based Terrestrial Beacon System (TB S) positioning for Evolved Universal Terrestrial Radio Access (E-UTRA) and is not associated with a cell.

DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A or B” and “A/B” mean (A), (B), or (A and B).

FIG. 1 illustrates a positioning architecture 100 for fifth generation system (5GS) applicable to positioning of a UE 104 with a next generation radio access network (NG-RAN) 108 in accordance with some embodiments. Except as otherwise described herein, the positioning architecture 100 and components described may be similar to the architecture and corresponding components described in Third Generation Partnership Project (3GPP) Technical Specification (TS) 38.305 v1.0.0 (2018 Mar. 12).

In some embodiments, the UE 104 may make measurements of downlink signals from the NG-RAN 108 or other sources such as evolved universal terrestrial radio access network (E-UTRAN), global navigation satellite system (GNSS), terrestrial beacon system (TBS), wireless local area network (WLAN) access points, Bluetooth beacons, UE barometric sensors, etc. the measurements to be made may be determined by a chosen or selected positioning method. The UE 104 may also contain location services (LCS) application 106 or access an LCS application either through communication with a network accessed by the UE 104 or through another application residing in the UE 104. The LCS application 106 may include or indicate the measurements and/or calculation functions to be used to determine the UE position (or geolocation) with or without network assistance.

The UE 104 may also include or implement one or more independent positioning functions and associated components (for example, GNSS/global positioning system (GPS) or the like), and the UE 104 may be able to report the UE position, independent of transmissions from the NG-RAN transmissions. In some embodiments, the UE 104 may report positioning information from these independent positioning functions/components, and this information may be used to assist the 5GS positioning determination. A UE 104 with an independent positioning functionality may also make use of assistance information obtained from the NG-RAN 108.

The NG-RAN 108 may include a next generation nodeB (gNB) 112 and a next generation evolved node B (ng-eNB) 116 coupled with one another by an Xn interface. The gNB 112 and ng-eNB 116 may be generically referred to as either base stations or access nodes.

The gNB 112 and ng-eNB may provide measurement information for the UE 104 and communicate the information to a location management function (LMF) 128.

The ng-eNB 116 may control several TPs 120, such as remote radio heads, PRS-only TPs for support of PRS-based TBS for E-UTRA, and/or the like. The ng-eNB 116 may further perform various measurements in response to requests from the LMF 128.

In addition, the UE 104 and access nodes may perform operations, procedures, processes, etc. of any of the previously described embodiments and/or any of the examples discussed infra, or portions thereof.

The NG-RAN 108 may be coupled with an access and mobility management function (AMF) 124 through respective NG-C interfaces between the AMF 124 and the ng-eNB 116 and the gNB 112.

The AMF 124 may receive a request for some location service associated with a particular target UE from another entity (for example, Gateway Mobile Location Center (GMLC)) or the AMF 124 itself may decide to initiate some location service on behalf of a particular target UE (for example, for an IMS emergency call from the UE 104). The AMF 124 may then send a LCS request to the LMF 128 over an NLs interface.

The LMF 128 may manage the support of different LCS for target UEs, including positioning of UEs and delivery of assistance data to UEs. The LMF 128 may interact with the access nodes that serve the UE 104 (for example, gNB 112 or ng-eNB 116) in order to obtain position measurements for the UE 104, including uplink measurements made by the ng-eNB 116 and downlink measurements made by the UE 104 that were provided to an ng-eNB 116 as part of other functions such as for support of handover. The LMF 128 may process the LCS request, which may include transferring assistance data to the UE 104 to assist with UE-based or UE-assisted positioning. Processing the LCS request may additionally/alternatively include positioning of the UE 104. The LMF 128 may then return the result of the location service back to the AMF 124 (for example, a position estimate for the UE 104 or an indication of any assistance data transferred to the UE 104). When the LCS is requested by an entity other than the AMF 124 (for example, a gateway mobile location center (GMLC)), the AMF 124 may return the LCS result to the requesting entity.

The LMF 128 may have a signaling connection to an Enhanced Serving Mobile Location Center (E-SMLC) 132, which may enable the LMF 128 to access information from an E-UTRAN (for example, to support the OTDOA for E-UTRA positioning method using downlink measurements obtained by the target UE of signals from eNBs and/or PRS-only TPs in E-UTRAN). The LMF 128 may also have a signaling connection to a secure user plane location (SUPL) Location Platform (SLP). The SLP is an SUPL entity responsible for positioning over the user plane.

The LMF 128 may also interact with any ng-eNB reachable from any of the AMFs with signaling access to the LMF 128 in order to obtain location-related information to support the OTDOA for E-UTRA positioning method, including PRS-based TBS for E-UTRA. The location-related information may include timing information for the TP in relation to either absolute GNSS time or timing of other TPs and information about the supported cells and TPs including PRS schedule.

The LMF 128 may interact with the UE 104 in order to deliver assistance data for a particular location service, if requested, or to obtain a location estimate if requested. For positioning of the UE 104, the L1VIF 128 may decide or select the position methods to be used. The decision/selection may be based on factors that may include an LCS Client type, required Quality of Service (QoS), UE positioning capabilities, gNB positioning capabilities, ng-eNB positioning capabilities, and/or other like factors. The LMF 128 may then invoke the determined/selected positioning methods in or at the UE 104, the gNB 112, or the ng-eNB 116. The positioning methods may yield a location estimate for the UE-based position methods or positioning measurements for UE-assisted and network-based position methods. The LMF 128 may combine all the received results and determine a single location estimate for the UE 104 (for example, hybrid positioning). Additional information such as accuracy of the location estimate and velocity may also be determined by the LMF 128 or at the UE 104, the gNB 112, or the ng-eNB 116.

In previous positioning methods, OTDOA is only available on E-UTRAN eNBs; and, for NR standalone (SA) operation, a UE could only be configured to measure inter-radio access technology (RAT) E-UTRAN reference signal time difference (RSTD) for OTDOA positioning. In such methods, an UE would receive a request from an LMF, and conduct an RSTD measurement on inter-RAT E-UTRAN cell. However, the LTE positioning protocol (LPP) signaling could not be decoded by the serving gNB, so the gNB would not configure any measurement gap for the UE OTDOA measurement.

Embodiments herein provide mechanisms for requesting measurement gap(s) for positioning measurements, for example, inter-RAT OTDOA measurements. For example, some embodiments describe the UE 104 requesting a measurement gap from serving access node for an inter-RAT RSTD measurement for OTDOA positioning purpose.

FIG. 2 illustrates messaging between components of the positioning architecture 100 in accordance with some embodiments. In particular, FIG. 2 illustrates messaging between the UE 104, an access node 204, and the LMF 128. The access node 204 may include one or more components of the NG-RAN 108 including, for example, gNB 112, ng-eNB 116, or TP 120.

The LMF 128 may send an LPP request location information message 208 (hereinafter “request 208”) to the UE 104. The request 208 may include an indication of OTDOA measurements that are requested and, may further include measurement configuration information to facilitate the measurements. In some embodiments, the request 208 may further include a required response time in which the measurements are to be performed.

The UE 104 may then send a measurement indication or gap request information message 212 (hereinafter “information message 212”) to the access node 204. The information message 212 may include information that will allow the access node 204 to facilitate the measurements that are to be performed by the UE 104.

In some embodiments, the information message 212 may be an inter-RAT RSTD/OTDOA Measurement Indication or an inter-frequency RSTD/OTDOA Measurement Indication sent to the serving gNB (for example, AN 204). As used herein, inter-RAT RSTD/OTDOA measurement may mean a positioning measurement that is to be performed on signals received from a node of a different RAT/frequency than the AN 204 (e.g., different RAT and different carrier frequency); and an inter-frequency RSTD/OTDOA measurement may mean a positioning measurement that is to be performed on signals from the same RAT (e.g., an NG-RAN), but on a carrier frequency different than that used by the AN 204 to serve the UE 104.

An inter-RAT or an inter-frequency RSTD/OTDOA measurement indication may include indications related to measurement gaps or positioning reference signals (PRSs). For example, in some embodiments, the indications may include indications of: a measurement gap repetition periodicity (MGRP); a measurement gap length (MGL); a measurement gap offset; a measurement gap pattern identifier/identity (ID) (for example, pattern ID between 0˜23); or a measurement gap type (for example, per-UE gap, or per-frequency range (FR) gap).

In some embodiments, the indications within the inter-RAT or an inter-frequency RSTD/OTDOA measurement indication may include OTDOA positioning assistance data. The OTDOA positioning assistance data may include, for example, indications of: a positioning reference signal (PRS) periodicity (for example, a PRS configuration index); a PRS time offset (based on, for example, a PRS configuration index); a PRS time duration (based on, for example, a PRS subframe number); or a PRS carrier frequency on which the UE 104 is to perform the positioning measurements.

In some embodiments, the information message 212 may be a measurement gap request sent to the serving gNB (for example, AN 204). Similar to the inter-RAT or inter-frequency RSTD/OTDOA measurement indications, unless as otherwise noted, the measurement gap request may include indications related to measurement gaps or PRSs.

For example, the measurement gap request may include indications of: an MGRP; an MGL; a measurement gap offset, a purpose of the requested measurement gap (for example, for positioning measurement); a measurement gap priority (for example, to indicate a priority of the requested measurement gap); a measurement gap pattern ID (for example, pattern ID between 0˜23); or a measurement gap type (for example, per-UE gap, or per-frequency range (FR) gap).

For another example, the measurement gap may include OTDOA positioning assistance data having indications of, for example: PRS periodicity (based on, for example, a PRS configuration index), a PRS time offset (based on, for example, a PRS configuration index), a PRS time duration (based on, for example, a PRS subframe number), or a PRS carrier frequency on which the UE 104 is to perform the positioning measurements.

In some embodiments, the AN 204 may operate an NR SA cell. For such an NR SA case, the UE 104 may provide, by transmission of the information message 212, for example, inter-RAT OTDOA/RSTD information (for example, carrier frequency and PRS-offset/gap-offset) to the AN 204 for a measurement gap. With respect to measurement gap patterns, since there may be 24 gap patterns, each having different MGRP and MGL, the AN 204 may assume that only one gap pattern (for example, gap pattern #0 having MGRP=40 ms and MGL=6 ms) may be used for inter-RAT RSTD measurement.

In some NR SA embodiments, when inter-RAT RSTD measurements are configured and the UE 104 desires measurement gaps for performing such measurements, only gap pattern #0 may be used. In some embodiments, the serving gNB may only configure gap pattern #0 (for example, MGRP=40 ms, MGL=6 ms) for UE inter-RAT OTDOA/RSTD measurement in NR SA case, while in other embodiments, the serving gNB (for example, AN 204) may configure any other gap pattern (for example, from 0˜23) for UE inter-RAT OTDOA/RSTD measurement in NR SA case based on an indication received from the UE in the information message.

In some NR embodiments, the positioning (for example, OTDOA/RSTD) measurements may have higher priority than other UE measurement activities. Thus, the AN 204 may reserve measurement gap resource for positioning (for example, OTDOA/RSTD) measurements without any sharing with other UE measurement activities. Said another way, the AN 204 may prioritize reservation of resources for the measurement gap for the positioning measurements over other UE activities.

At 216, the UE 104 may perform the positioning measurements. The positioning measurements may be performed by the UE 104 based on signals, for example, PRSs, transmitted by access nodes in other frequencies or RATs. The positioning measurements may be performed within the measurement gaps configured by the AN 204 and may otherwise be similar to the above discussion with respect to FIG. 1.

The UE 104 may then encode and send an LPP provide location information message 220 (hereinafter also referred to as “provide information message 220”) the LMF 128. The provide information message 220 may include any positioning measurements obtained by the UE 104, for example, at 216.

In some embodiments, the UE 104 may send the provide information message 220 to the LMF 128 before the response time, provided in the request information message 208, expires. In some embodiments, the UE 104 may have a timer that is set with the response time, upon receipt, in order to monitor this response time period. If the UE 104 is unable to perform the requested measurements, or the response time has elapsed before any of the requested measurements were obtained, the UE 104 may return any information that can be provided in the provide information message 220 and may further include a cause indication for information requested but not provided.

FIG. 3 illustrates an operation flow/algorithmic structure 300 in accordance with some embodiments. The operation flow/algorithmic structure 300 may be performed or implemented by a UE (for example, UE 104) or components thereof (for example, baseband or application circuitry) as described herein.

The operation flow/algorithmic structure 300 may include, at 304, receiving a request for location information. In some embodiments, the request may be an LPP request location information message from the LMF 128 as described above with respect to FIG. 2. Receipt of the request for location information may include a number of receive operations including, not limited to, decoding, de-mapping, demodulating, processing, etc. these operations may be performed by one or more components of the UE 104 to obtain the information transmitted in the request.

In some embodiments, while the request is received from a serving access node, the contents included therein may be transparent, or not otherwise available, to the serving access node. In some embodiments, the request may be received from the gNB over an NR-Uu interface.

The operation flow/algorithmic structure 300 may further include, at 308, encoding a measurement indication or measurement gap request. The measurement indication or measurement gap request may be encoded to include information that is to be transmitted to the serving access node to facilitate positioning measurements that are to be performed by the UE 104. In some embodiments, the measurement indication or measurement gap request may be similar to the information message 212 described above with respect to FIG. 2.

In some embodiments, a first component of the UE 104 (for example, application circuitry) may determine the information that is to be transmitted to the serving access node, while a second component of the UE 104 (for example, baseband circuitry) may encode the information into the measurement indication or measurement gap request. Furthermore, a third component of the UE 104 (for example, radio-frequency circuitry) may cause the encoded measurement indication or measurement gap request to be transmitted to the serving access node over the air (for example, the gNB 112 over the NR-Uu interface).

The information included in the measurement indication or measurement gap request may be similar to that described above with respect to FIG. 2.

The operation flow/algorithmic structure 300 may further include, at 312, performing measurements based on the request. The measurements, which may be OTDOA/RSTD measurements, may be performed on one or more inter-RAT or inter-frequency signals (for example, PRSs). The performance may be similar to that described above with respect to FIG. 1 and may be performed within a measurement gap configured by the serving access node.

The operation flow/algorithmic structure 300 may further include, at 316, encoding a report for transmission. The report may include the results of the positioning measurements requested at 304. In some embodiments, the report may be similar to, for example, the LPP provide location information message 220 described above with respect to FIG. 2.

The report may be encoded for transmission (by one or more other components of the UE 104) to the requesting LMF (for example, LMF 128). In some embodiments, the report may be transmitted to the serving access node (for example, AN 204) over the LTE-Uu interface or the NR-Uu interface. The serving access node may then forward the report to the LMF 128 over an NG-C interface.

FIG. 4 illustrates an operation flow/algorithmic structure 400 in accordance with some embodiments. The operation flow/algorithmic structure 400 may be performed or implemented by an access node (for example, AN 204) or components thereof (for example, baseband or application circuitry of gNB 112) as described herein.

The operation flow/algorithmic structure 400 may include, at 404, receiving positioning information. The positioning information may be received in a message such as, for example, the measurement indication or gap request information message 212 described above with respect to FIG. 2.

Receiving the positioning information may include a variety of operations performed by one or more components of the AN 204. These operations may include, for example, decoding, de-mapping, demodulating, etc.

The positioning information may be information related to a measurement gap or positioning reference signals, similar to that described above with respect to FIG. 2.

The operation flow/algorithmic structure 400 may include, at 408, configuring a measurement gap for the UE 104 to perform positioning measurements. In some embodiments, the configuring of the measurement gap may include the AN 204 scheduling communications within one or more cells controlled by the AN 204 in manner to eliminate or otherwise reduce signals that have the potential of interfering with the positioning measurements.

In some embodiments, the configuration at 408 may include generation and transmission of one or more configuration messages to UEs, neighbor access nodes, etc.

In some embodiments, the AN 204 may prioritize reservation of resources for the measurement gap, configured at 408, over other activities performed by the UE 104.

FIG. 5 illustrates an architecture of a system 500 of a network in accordance with some embodiments. In general, components of the system 500 may be similar to and substantially interchangeable with like-named components of FIG. 1.

The system 500 is shown to include a UE 501 and a UE 502, either or both of which may correspond to UE 104. As used herein, the term “user equipment” or “UE” may refer to a device with radio communication capabilities and may describe a remote user of network resources in a communications network. The term “user equipment” or “UE” may be considered synonymous to, and may be referred to as client, mobile, mobile device, mobile terminal, user terminal, mobile unit, mobile station, mobile user, subscriber, user, remote station, access agent, user agent, receiver, radio equipment, reconfigurable radio equipment, reconfigurable mobile device, etc. Furthermore, the term “user equipment” or “UE” may include any type of wireless/wired device or any computing device including a wireless communications interface. In this example, UEs 501 and 502 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing device, such as consumer electronics devices, cellular phones, smartphones, feature phones, tablet computers, wearable computer devices, personal digital assistants (PDAs), pagers, wireless handsets, desktop computers, laptop computers, in-vehicle infotainment (IVI), in-car entertainment (ICE) devices, an Instrument Cluster (IC), head-up display (HUD) devices, onboard diagnostic (OBD) devices, dashtop mobile equipment (DME), mobile data terminals (MDTs), Electronic Engine Management System (EEMS), electronic/engine control units (ECUs), electronic/engine control modules (ECMs), embedded systems, microcontrollers, control modules, engine management systems (EMS), networked or “smart” appliances, machine-type communications (MTC) devices, machine-to-machine (M2M), Internet of Things (IoT) devices, and/or the like.

In some embodiments, any of the UEs 501 and 502 can comprise an Internet of Things (IoT) UE, which can comprise a network access layer designed for low-power IoT applications utilizing short-lived UE connections. An IoT UE can utilize technologies such as machine-to-machine (M2M) or machine-type communications (MTC) for exchanging data with an MTC server or device via a public land mobile network (PLMN), Proximity-Based Service (ProSe) or device-to-device (D2D) communication, sensor networks, or IoT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An IoT network describes interconnecting IoT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The IoT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the IoT network.

The UEs 501 and 502 may be configured to connect, e.g., communicatively couple, with a radio access network (RAN) 510. The RAN 510 may be, for example, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. The UEs 501 and 502 utilize connections (or channels) 503 and 504, respectively, each of which comprises a physical communications interface or layer (discussed in further detail infra). As used herein, the term “channel” may refer to any transmission medium, either tangible or intangible, which is used to communicate data or a data stream. The term “channel” may be synonymous with and/or equivalent to “communications channel,” “data communications channel,” “transmission channel,” “data transmission channel,” “access channel,” “data access channel,” “link,” “data link,” “carrier,” “radiofrequency carrier,” and/or any other like term denoting a pathway or medium through which data is communicated. Additionally, the term “link” may refer to a connection between two devices through a Radio Access Technology (RAT) for the purpose of transmitting and receiving information. In this example, the connections 503 and 504 are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a Global System for Mobile Communications (GSM) protocol, a code-division multiple access (CDMA) network protocol, a Push-to-Talk (PTT) protocol, a PTT over Cellular (POC) protocol, a Universal Mobile Telecommunications System (UMTS) protocol, a 3GPP Long Term Evolution (LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR) protocol, and the like.

In this embodiment, the UEs 501 and 502 may further directly exchange communication data via a ProSe interface 505. The ProSe interface 505 may alternatively be referred to as a sidelink (SL) interface comprising one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH). In various implementations, the SL interface 505 may be used in vehicular applications and communications technologies, which are often referred to as V2X systems. V2X is a mode of communication where UEs (for example, UEs 501, 502) communicate with each other directly over the PC5/SL interface 505 and can take place when the UEs 501, 502 are served by RAN nodes 511, 512 or when one or more UEs are outside a coverage area of the RAN 510. V2X may be classified into four different types: vehicle-to-vehicle (V2V), vehicle to-infrastructure (V2I), vehicle-to-network (V2N), and vehicle-to-pedestrian (V2P). These V2X applications can use “co-operative awareness” to provide more intelligent services for end-users. For example, vehicle UEs (vUEs) 501, 502, RAN nodes 511, 512, application servers 530, and pedestrian UEs 501, 502 may collect knowledge of their local environment (for example, information received from other vehicles or sensor equipment in proximity) to process and share that knowledge in order to provide more intelligent services, such as cooperative collision warning, autonomous driving, and the like. In these implementations, the UEs 501, 502 may be implemented/employed as Vehicle Embedded Communications Systems (VECS) or vUEs.

The UE 502 is shown to be configured to access an access point (AP) 506 (also referred to as “WLAN node 506”, “WLAN 506”, “WLAN Termination 506” or “WT 506” or the like) via connection 507. The connection 507 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.11 protocol, wherein the AP 506 would comprise a wireless fidelity (WiFi®) router. In this example, the AP 506 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below). In various embodiments, the UE 502, RAN 510, and AP 506 may be configured to utilize LTE-WLAN aggregation (LWA) operation and/or WLAN LTE/WLAN Radio Level Integration with IPsec Tunnel (LWIP) operation. The LWA operation may involve the UE 502 in RRC_CONNECTED being configured by a RAN node 511, 512 to utilize radio resources of LTE and WLAN. LWIP operation may involve the UE 502 using WLAN radio resources (e.g., connection 507) via Internet Protocol Security (IPsec) protocol tunneling to authenticate and encrypt packets (e.g., interne protocol (IP) packets) sent over the connection 507. IPsec tunneling may include encapsulating entirety of original IP packets and adding a new packet header, thereby protecting the original header of the IP packets.

The RAN 510 can include one or more access nodes 511 and 512 that enable the connections 503 and 504. The access nodes 511 and 512 may correspond to and be substantially interchangeable with AN 204.

As used herein, the terms “access node,” “access point,” or the like may describe equipment that provides the radio baseband functions for data and/or voice connectivity between a network and one or more users. These access nodes can be referred to as base stations (BS), NodeBs, evolved NodeBs (eNBs), gNBs, ng-eNBs, RAN nodes, Road Side Units (RSUs), and so forth, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). The term “Road Side Unit” or “RSU” may refer to any transportation infrastructure entity implemented in or by a gNB/eNB/RAN node or a stationary (or relatively stationary) UE, where an RSU implemented in or by a UE may be referred to as a “UE-type RSU”, an RSU implemented in or by an eNB may be referred to as an “eNB-type RSU.”

Any of the RAN nodes 511 and 512 can terminate the air interface protocol and can be the first point of contact for the UEs 501 and 502. In some embodiments, any of the RAN nodes 511 and 512 can fulfill various logical functions for the RAN 510 including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management.

In accordance with some embodiments, the UEs 501 and 502 can be configured to communicate using Orthogonal Frequency-Division Multiplexing (OFDM) communication signals with each other or with any of the RAN nodes 511 and 512 over a multicarrier communication channel in accordance with various communication techniques, such as, but not limited to, an Orthogonal Frequency-Division Multiple Access (OFDMA) communication technique (e.g., for downlink communications) or a Single Carrier Frequency Division Multiple Access (SC-FDMA) communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

In some embodiments, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes 511 and 512 to the UEs 501 and 502, while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot. Such a time-frequency plane representation is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are several different physical downlink channels that are conveyed using such resource blocks.

The physical downlink shared channel (PDSCH) may carry user data and higher-layer signaling to the UEs 501 and 502. The physical downlink control channel (PDCCH) may carry information about the transport format and resource allocations related to the PDSCH channel, among other things. It may also inform the UEs 501 and 502 about the transport format, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request) information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE 502 within a cell) may be performed at any of the RAN nodes 511 and 512 based on channel quality information fed back from any of the UEs 501 and 502. The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs 501 and 502.

The PDCCH may use control channel elements (CCEs) to convey the control information. Before being mapped to resource elements, the PDCCH complex-valued symbols may first be organized into quadruplets, which may then be permuted using a sub-block interleaver for rate matching. Each PDCCH may be transmitted using one or more of these CCEs, where each CCE may correspond to nine sets of four physical resource elements known as resource element groups (REGs). Four Quadrature Phase Shift Keying (QPSK) symbols may be mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the downlink control information (DCI) and the channel condition. There can be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation level, L=1, 2, 4, or 8). [75] Some embodiments may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some embodiments may utilize an enhanced physical downlink control channel (EPDCCH) that uses PDSCH resources for control information transmission. The EPDCCH may be transmitted using one or more enhanced control channel elements (ECCEs). Similar to above, each ECCE may correspond to nine sets of four physical resource elements known as an enhanced resource element groups (EREGs). An ECCE may have other numbers of EREGs in some situations.

The RAN 510 is shown to be communicatively coupled to a core network (CN) 520 via an S1 interface 513. In embodiments, the CN 520 may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN.

The core network 520 may include an AMF 514 and an LMF 515, which may be similar to AMF 124 and LMF 128 described above.

Furthermore, the AMF 514 may be responsible for registration management (e.g., for registering UEs, etc.), connection management, reachability management, mobility management, and lawful interception of AMF-related events, and access authentication and authorization. Furthermore, AMF 514 may be a termination point of RAN CP interface, which may include or be an N2 reference point between the (R)AN XR11 and the AMF 514; and the AMF 514 may be a termination point of NAS (N1) signalling, and perform NAS ciphering and integrity protection.

AMF 514 may also support NAS signalling with a UE (501 or 502) over an N3 interworking-function (IWF) interface. The N3IWF may be used to provide access to untrusted entities.

In alternative implementations, both millimeter wave and sub-millimeter wave radio functions may be implemented in the same physical radio front end module 610.

Nodes or satellites of the navigation satellite constellation(s) (“GNSS nodes”) may provide positioning services by continuously transmitting or broadcasting GNSS signals along a line of sight, which may be used by GNSS receivers (for example, positioning circuitry 645 and/or positioning circuitry implemented by UEs 701, 702, or the like) to determine their GNSS position. The GNSS signals may include a pseudorandom code (for example, a sequence of ones and zeros) that is known to the GNSS receiver and a message that includes a time of transmission (ToT) of a code epoch (for example, a defined point in the pseudorandom code sequence) and the GNSS node position at the ToT. The GNSS receivers may monitor/measure the GNSS signals transmitted/broadcasted by a plurality of GNSS nodes (for example, four or more satellites) and solve various equations to determine a corresponding GNSS position (for example, a spatial coordinate). The GNSS receivers also implement clocks that are typically less stable and less precise than the atomic clocks of the GNSS nodes, and the GNSS receivers may use the measured GNSS signals to determine the GNSS receivers' deviation from true time (for example, an offset of the GNSS receiver clock relative to the GNSS node time). In some embodiments, the positioning circuitry 645 may include a Micro-Technology for Positioning, Navigation, and Timing (Micro-PNT) IC that uses a master timing clock to perform position tracking/estimation without GNSS assistance.

The GNSS receivers may measure the time of arrivals (ToAs) of the GNSS signals from the plurality of GNSS nodes according to its own clock. The GNSS receivers may determine time of flight (ToF) values for each received GNSS signal from the ToAs and the ToTs, and then may determine, from the ToFs, a three-dimensional (3D) position and clock deviation. The 3D position may then be converted into a latitude, longitude and altitude. The positioning circuitry 645 may provide data to application circuitry 605, which may include one or more of position data or time data. Application circuitry 605 may use the time data to synchronize operations with other radio base stations (for example, RAN nodes 511, 512, or the like).

The platform 700 may also include interface circuitry (not shown) that is used to connect external devices with the platform 700. The external devices connected to the platform XT00 via the interface circuitry may include sensors 721, such as accelerometers, level sensors, flow sensors, temperature sensors, pressure sensors, barometric pressure sensors, and the like. The interface circuitry may be used to connect the platform 700 to electro-mechanical components (EMCs) 722, which may allow platform 700 to change its state, position, and/or orientation, or move or control a mechanism or system.

In embodiments, platform 700 may be configured to operate one or more EMCs 722 based on one or more captured events and/or instructions or control signals received from a service provider and/or various clients.

In some implementations, the interface circuitry may connect the platform 700 with positioning circuitry 745, which may be the same or similar as the positioning circuitry 645 discussed with regard to FIG. 6.

The power management integrated circuitry (PMIC) 725 (also referred to as “power management circuitry 725”) may manage power provided to various components of the platform 700. In particular, with respect to the baseband circuitry 710, the PMIC 725 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMIC 725 may often be included when the platform 700 is capable of being powered by a battery 730, for example, when the device is included in a UE 104, 501, or 502.

In some embodiments, the PMIC 725 may control, or otherwise be part of, various power saving mechanisms of the platform 700. For example, if the platform 700 is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the platform 700 may power down for brief intervals of time and thus save power. If there is no data traffic activity for an extended period of time, then the platform 700 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The platform 700 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The platform 700 may not receive data in this state, in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

A battery 730 may power the platform 700, although in some examples the platform XT00 may be mounted deployed in a fixed location, and may have a power supply coupled to an electrical grid. The battery 730 may be a lithium ion battery, a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like. In some implementations, such as in V2X applications, the battery 730 may be a typical lead-acid automotive battery.

In some implementations, the battery 730 may be a “smart battery,” which includes or is coupled with a Battery Management System (BMS) or battery monitoring integrated circuitry. The BMS may be included in the platform 700 to track the state of charge (SoCh) of the battery 730. The BMS may be used to monitor other parameters of the battery 730 to provide failure predictions, such as the state of health (SoH) and the state of function (SoF) of the battery 730. The BMS may communicate the information of the battery 730 to the application circuitry 705 or other components of the platform 700. The BMS may also include an analog-to-digital (ADC) convertor that allows the application circuitry 705 to directly monitor the voltage of the battery 730 or the current flow from the battery 730.
